  • Abstract:
  • Electric vehicles require structurally efficient under-body floor panels capable of supporting heavy battery packs while maintaining lightweight characteristics. The floor panel significantly influences vehicle stiffness, crashworthiness, durability, and battery protection. Conventional floor structures are often unsuitable for direct battery integration due to increased loading and stress concentration. This research focuses on the design optimization and structural analysis of an electric vehicle under-body floor panel. A three-dimensional CAD model was developed and modified by introducing reinforcement ribs and battery mounting provisions. Finite Element Analysis (FEA) was performed using ANSYS Workbench to evaluate total deformation, equivalent stress, and equivalent strain under battery and passenger loading conditions. The optimized floor panel exhibited improved structural stiffness and reduced deformation compared to conventional designs. The study demonstrates that floor panel optimization enhances battery safety, structural performance, and overall vehicle efficiency.
